Metal Tech 2003-09 Lexus GX470 Rear Long Travel Coil Springs Heavy

Metal-tech 4x4 Next Gen dual rate Long Travel heavy rear springs.

Since the 2003-09 Lexus GX470 does not capture the coil spring, the suspension travel is limited to the free height of the spring (ie the total length of the spring) before the spring will fall out of the coil buckets.  By creating the dual-rate rear heavy springs we have the bottom half of the spring doing all the suspension work as the top half stays fully collapsed at ride height.  When the suspension starts to cycle downwards the top half of the spring starts to open up allowing for greater suspension travel over a standard 2" lift spring.

We have taken the knowledge and performance we have gained over the past 5yrs of our long travel systems and wrapped it into the single best performing NextGen 2003-09 Lexus GX470 spring to date. We have increased the available height by 1" over our first generation spring. The NextGen rear heavy springs have increased load capacity similar to our previous HD springs, however, it maintains the ride and comfort of our previous Med spring even with the lightest loaded trucks due to the new dual-rate build.
